IMPROVEMENT IN BARN-DOOR FA STENINGS.

Specification forming part of Letters Patent No. 135,027, dated January 21, 1873.

To all whom it may concern:

Be it known that we, ALAMANDER D. WRIGHT and AUREN RoYs, of Belleville, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Barn-Door Fastenings; and we do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which- Figure 1 is a perspective view of a pair of doors from the inner side of a barn, one of the doors being partially open 5 Fig. 2 is an elevation of the outer edge of a door swung open and locked; and Fig. 3 is a detached perspective view of one of the cam-latches.

Like letters refer to like parts in each figure.

This invention relates to a fastening for barn and other large doors designed to automatically lock the door at top and bottom" when closed, and to latch it to the side of the building when swung fully open, and to be operated by a single thumb-latch. The invention consists in thearrangement of a combined bolt and gravity latch for locking the bottom andthe top of the door, and of a thumb-latch so arranged as to unfasten both from the outside of the door; also, in the arrangement of said thumb-latch in such a way .as to lock the door in its open position, as more fully hereinafter set forth.

In the drawing, A represents a portion of the sill of abarn; B, the upper floor-plate; and O O,the door-posts, to which are hung the doors D D. a a are stops nailed to the under side of the floor-plate, and b b are similar stops on the door-sill below, all said stops being beveled on their outer sides, making inclined planes of them, whose back faces are in line with the backs of the battens D of the doors. Near the top of the door we nail a block, E,.as thick as the batten, and to this block we'pivot a cam-latch, F, of the form shown-in Fig. 3. To the shorter end of this cam-latch is pivoted the top end of a long bar or bolt, Gr, whose lower end is slotted and secured, by a bolt, 0, to the door in such a way as to allow it to play freely up and down.

When the lower end of said bolt G drops behind the stop b the latch F will be rotated on its pivot so as to bring its top end behind the stop a. Raising the bar disengages it and the latch from the stops,-when the door may be opened. The latch and lower end of the bar being beveled inwardly, the bar is easily raised in passing over the stop.

H is a thumb-latch pivoted in a mortise through the door. I is a staple driven into the edge of the bolt G, embracing the inner end of the latch H. By depressing the outer end of this latch a person can unfasten the door from the outside.

In the upper face of the outer end of the latch is cut a notch, from which the end of the latch is rounded off, as seen in Fig. 2, so that when the door is swung around to the face of the barn it will pass under and engage with the point of a hook, J, nailed to the barn, the weight of the bolt on the other end of the latch-lever insuring such engagement, thus locking the door in the open position, from which it may be released by raising the bar G.

The advantages of this device are, that the door locks itself open or closed; the lock is easily operated, and, with exception of the staple and pivots, may be made entirely of wood, and at a small cost.

What we claim as our invention, and desire to secure by Letters Patent, is-

The combination of the vertically-moving bolt G and the swinging latch F with suitable catches, the parts operating substantially as described, for the purpose set forth.
